//column width
 ((Excel.Range)xlWorkSheet.Cells[2, 3]).EntireColumn.ColumnWidth = 45;
//Align center for text
 xlWorkSheet.get_Range("c11", dstrowcount).Columns.HorizontalAlignment = 3;
//merging cells
 xlWorkSheet.get_Range("e2", "j2").Cells.Merge();
//color chage for selected text
 Excel.Range range = xlWorkSheet.get_Range("d5");
 range.get_Characters(1, 5).Font.ColorIndex = 14;
//border color & lines settings
xlWorkSheet.get_Range("c11", dstrowcount).Borders.LineStyle = Excel.XlLineStyle.xlContinuous;
xlWorkSheet.get_Range("c11", dstrowcount).Borders.ColorIndex = 15;
